Gloss measurement uses visible light with a 75° angle of incidence on the paper surface. Gloss is a property that expresses the ability of a surface to show the gloss appearance or gloss quality. BS EN 14086 gives information about the importance, methodology and test methods of gloss which is one of the optical properties of the paper.
BS EN 14086 specifies a photometric test method for the assessment of visual gloss by means of a reflectometer value measured at an angle of 45°. BS EN 14086 is applicable to plain paper and board surfaces of high gloss, commonly called glossy papers and boards, having reflectance values, measured according to BS EN 14086, above approximately 7. Materials containing optical brightening agents may be measured.
BS EN 14086 on gloss measurement of paper and board is useful for:
Gloss is a measure of the optical reflectance of the paper surface. Since gloss is important for visual impact and is a significant component of paper printability, it is an essential measurement parameter for the producers of fine and coated grades, super-calendared, publication grades and coated boards.
The reflectometer value is determined by averaging the reflection in a defined angular region cantered in the specular direction. BS EN 14086 describes measurement at an angle of incidence of 45° using a parallel beam geometry commonly known as the 45° DIN method.
BS EN 14086 guides you with gloss measurement of paper and boards and also creates a standardized approach for the measurement of reflectometer values. BS EN 14086 helps in the early detection of wrong applications and saves time and effort. Also, it helps in determining the degradation in the coating as exposed to real working conditions.
